Ghost Walker is BrewDog's alcohol-free IPA, made in collaboration with metal band Lamb of God and brewed at their Canal Winchester, Ohio facility. Billed as the world's first non-alcoholic collaboration beer, it was launched in April 2020 alongside the video premiere of Lamb of God performing Ghost Walking, the song the beer takes its name from. The beer is hop-forward, with tropical aromas alongside grassy and pine, underpinned by a solid malt baseline.
